Better Support for Known Tracelogging Events

[shmuelie]

Right now, all tracelogging (aka self-describing) events can't really have strong typing information. This makes usage of them very hard. I would love to have a way to create strongly typed version of them, similar to what is supported for Manifest events.

I have not experimented with this, but it does seem do-able. TraceLogging support is somewhat bolted on in TraceEvent and is mostly handled by DynamicTraceEventParser. I suspect it would be possible to implement such a thing by creating a new TraceLoggingTraceEventParser similar to DynamicTraceEventParser that can return a strongly-typed payload from an event-specific property. Instead of keeping track of the event in the main lookup logic of TraceEvent as is done for manifested events, it would register itself as a dynamic parser, and would keep its own internal lookup table of event --> strongly typed template.

There has not been significant interest in this area which is why nothing has been done here. I would certainly support such a change if you were interested in contributing it.

That was my thinking as well. I might see about playing around with it if/when I have time 😅
